Description
Summary:Promising future nanoscopic devices: Azobenzene polypeptides can be switched between an elongated trans and a compact cis conformation. Molecular dynamics simulations have been carried out to probe their elastic properties and to explain recent scanning probe microscopy experiments at the atomic level. The results should enable the rational design of photoswitchable polymers, as demonstrated by a first example.
